I'm trying to use ApiGatewayV2Client::get_apis to get a list of apis, but it returns an empty list (the GetApisResponse::items vector is empty). After enabling logging I can see that the response status is 200 and it contains apis' information:

{
    "items": [
        {"apiId" : "0ei2qoop3g", "name" : "test_api", "protocolType" : "HTTP", ... },
        { ...other apis... }
    ]
}

All field names start with a lowercase letter, and the corresponding rusoto structure expects upper-cased field names (for example "ProtocolType" instead of "protocolType").

As far as I can see, the declaration from which rusoto structures are generated also contains fields starting from an upper-cased character. I'm not sure on which side the issue is, but the similar code using Python boto3 SDK is working as expected:

response = self.apigw.get_apis()

for item in response['Items']:
    print(item['ApiId'])
    print(item['Name'])

I could submit a pull request that changes GetApisResponse and Api structs declaration, but changing the generated code feels slightly wrong.
